REVERSIBLE CARD-INDEX HOLDER.

Application led November 19, 1919,4Sria1 No. 339,251. Renewed July 23,1925.

To all whom t may concern.:

Be it known that I, FRANK H. JonNs'roN, a citizen of theUnited States,residing in the city of Chicago, county of Cook, and

State of Illinois, have invented certain new and useful Improvements inReversible Card-Index Holders, kof which the following is aspeciiication.

My invention relates to improvements in reversible card index holdersand refers more particularly to holders adapted for use in file cabinetsor the like.

It has among its salient objects to provide a holder which is held inthe drawer. of a cabinet; to provide a holder with index cards mountedupon both sides and adapted to be reversed so that entries may be madeon the cards on either side; to provide a reversible card index holderwhich may be reversed when the drawer is withdrawn from the cabinet andis hinged in either a vertical or horizontal plane so that when theholder is reversed it will lie in identically the same position in thedrawer, no matter which side is being used; to provide a reversible cardindex holder which has the drawer as a support when entries are beingmade on the cards on either side of the holder.

There are numerous ways in which the holder may be reversed making itpossible to use'twice the number of cards upon the holders as aregenerally available on holders in card index cabinets. The first andmost obvious being simply to lay the reversible holder in the drawer andremove it to reverse it. This is rather awkward in operation and has theadded disadvantage that holders may be removed and misplaced, and forthat reason I suggest the following modiications.

In the drawings:

Fig. 1 is the reversible holder and drawer showing stud and groovereversing device.

Fig. 2 is a sectional edge view of assembly shown in Fig. 1.

Fig. 3 is a sectional view of the end of the drawer shown in Fig. 1,with parts Abroken away.

" Fig. 4 is a fragmentary detail of top of the holder.

Fig. 5 is a holder with vertical hinges.

Fig. 6 is an edge view of side reversing hinge arrangement, shown inFig. 5. Figs.

5 and 6 are modifications of holder in Fig. l.

Fig. 7 is a fragmentary detail of the side of the holder shown in Fig.`8.

Fig. 8 is an edge view of top pivoting rod or hinge; a secondmodification ofthe reversible holder.

Fig. 9 is an end view of the end revolving 60 hinges; a thirdmodification of the reversible holder. x

Referring in detail to the drawings, there are four means shown'forreversing the card holder 1 in the drawer 2. In Figs. 1, 2 and 3, theslottedend pieces 3 in the drawer are engaged b studs 4 on the holdersliding therem. igs. 5 and 6 show the side hinges' 5 pivoted at 6 to thedrawer and at 7 to the holder, thus allowing the holder to be reversed,end for end, 1n the drawer. It will be noticed in Fi 6 that the cards 8on the underside of t e holder-lie in a reversed position so that theywill be properly arranged when the holder is reversed.

In Fig. 9, the hinges 9 are placed at the top and bottom of the holder(the bottom end only is shown as the top is identical with it) and arepivoted at the center 10 to the drawer and at 11 to the holder. Withthis arrangement, the holder is reversed, edge for edge, asincombination shown in Fig. 1. The method shown in Fig. 8 has the holderpivoted at 12. When the drawer is open, the front end of the holder maybe lifted and turned back and entries made on the cards arranged inreverse order.

The card holders are of the usual design having lateral channels 13which assist in supporting the cards. The end pieces 3 of the drawersare high enough to allow clearz ance between the cabinet (not shown) andthe cards when the drawers are slid out and in. Therunners 14 are iixedto the bottom of the drawers and make the operation of the drawerseasier.

It has been the usual .practice when using a card index cabinet to havecards mounted only upon one side of the holder in the drawer. With myinvention, both sides of the holder can be used for cards and witheither side up the holder will be sup orted so that there will be a firmwriting ack for making entries upon the cards.

It is not my intention to restrict myself to these means of reversingthe holders, but I elongated slots in opposite end portionsthereof, of areversible card index holder adapted to be carried b said drawer andmovable therewith, stu s projecting from Said holder and entering saidslots in the ends of the drawer, said holder beingshiftable bodilyrelative to said drawer by a movement of the studs in said slots topermit the holder to be reversed.

2. In a reversible card index holder, the combination with a slidingdrawer, the end portions of said drawer having elongated slots thereindisposed in substantially the same horizontal plane, a reversible cardindex holder carried by said drawer and movable therewith, studsdisposed near one 1ongitudin'al edge of said card holder at each endthereof, said studs being adapted to enter the slots in the end portionsof said drawer and slidable therein relative to said end portions topermit the holder to be moved relative to the drawer to reverse' theexposed side thereof.

3. In an index holder, the combination with a sliding drawer, of areversible card index holder carried by said drawer and movabletherewith, means connecting said holder with said drawer, said meanspermitting a sliding bodily movement of the holder relative to thedrawer to permit the exposed portion of said holder to be reversed,substantally as described.
